Abstract: The invention relates to a multi-carrier transmission system, particularly a DMT system, in which data is transmitted between two transceivers using a plurality of carriers, the frequency bandwidth of the system being divided between said plurality of carriers, the transmission system being adapted for operation in a heterogeneous network including a number of subscriber equipments having different channel characteristics and coexisting on the same cable, the length of cable for each subscriber terminal varying in dependence on their respective locations. In accordance with the invention the transmission system includes allocation means for allocating the traffic of subscriber equipments having a shorter length of cable to tones starting from a higher frequency band of said system bandwidth.

Abstract: One problem, frequently encountered with VDSL transmission systems, is that upstream FEXT produced by system users having short wires can be very strong. Users having shorter wires get high bit rates whereas users having longer wires get low bit rates. In extreme cases it may happen that users with wire lengths greater than 1000 metre cannot transmit data upstream. The present invention provides a VDSL transmission system with a plurality of modems. The modems are located at varying distances from a central station. There is a target bit rate for each modem. These modems on shorter wires have control means for reducing their transmit power. This reduces the FEXT produced by these modems enabling modems on longer wires to transmit at higher bit rates.

Abstract: The present invention relates to a receiver for use in an OFDM type transmission system, in which data is transmitted in frames. Each frame has a cyclic prefix which is a repetition of part of the frame. Control means are provided and the control means controls a sampling oscilator. The control means include estimation means for estimating timing deviations of the sampling clock. The estimation means operates entirely on frequency domain input data.
